The 9895A returns the results of the last self-test it has
performed. This
is useful after the Initiate Self-Test com-
mand or after the 9895A has been powered on (it performs
a self-test
at power on).
After receiving the self-test secondary, the 9895A makes
two bytes of the self-test results available. The
second byte
will be tagged with an EOI.
